Abstract
The invention discloses a control switch contact resistance detector. The detector comprises a detection probe which is connected with the output end of a contact of a static contactor of a control switch through a lead; a detection signal of the detection probe is transmitted into a resistance tester; a test result signal of the resistance tester is transmitted into a PLC (Programmable Logic Controller); and the PLC is used for judging and processing the test result signal and comparing the test result signal with a set resistance value, is connected with an alarm device for giving an alarm, and controls a servo motor capable of driving a main shaft of the control switch. According to the structure of the control switch contact resistance detector, the whole detector replaces the conventional manual operation; a product is put into a jig, an operation button is pressed down, the servo motor drives the command switch to rotate, the rotation angle of the command switch is controlled by a PLC program, and then contact resistance of each gear of the control switch is detected; and when some product is unqualified, the alarm device gives an alarm automatically. The control switch contact resistance detector is simple and convenient to use, and can improve detection efficiency and ensure detection quality.
Description
Technical field
The present invention relates to a kind of control switch contact resistance pick-up unit.
Background technology
Control switch refers to according to the master control electrical apparatus of preset program conversion control circuit wiring, it comprises a pair of moving contact that driven by main shaft and the many group static contact contact corresponding with moving contact, in order to guarantee the qualification of product, therefore manufacturer need to detect the contact resistance of control switch, it is all by manually operated that existing contact resistance detects, when detection, manually switch is pushed to the gear that needs test, then by testing tool clip testing contact resistance on corresponding terminal, the problem that adopts existing detection method to exist is: on the one hand, manual operation efficiency lower (switch that gear is more is more obvious), manual operation easily causes few inspection, undetected situation to occur on the other hand.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can improve detection efficiency, guarantees to detect the control switch contact resistance pick-up unit of quality.
In order to solve the problems of the technologies described above, control switch contact resistance pick-up unit of the present invention, comprise the detection probe being connected with the output terminal of control switch static contact contact by lead-in wire, the detection signal of detection probe outputs in a resistance meter, the test result signal of resistance meter outputs in a PLC, by PLC, test result signal judged and process and compare with the resistance of setting, on PLC, be also connected with the warning device that can report to the police, PLC controls a servomotor that can drive the main shaft of control switch simultaneously.
Adopt structure of the present invention, replace traditional manual operation by a whole set of pick-up unit arranging, only needed workman that product is put into tool, then push button, the rotation of driven by servomotor command switch, the angle that can rotate by PLC programmed control, detects the contact resistance of each gear of control switch, simultaneously in the time having underproof product, the warning device arranging in pick-up unit can automatic alarm, easy to use, improve detection efficiency, guarantee detection quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of control switch contact resistance pick-up unit of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, control switch contact resistance pick-up unit of the present invention is described in further detail.
As shown in the figure, control switch contact resistance pick-up unit of the present invention, comprise the detection probe being connected with the output terminal of control switch static contact contact by lead-in wire, the detection signal of detection probe outputs in a resistance meter, the test result signal of resistance meter outputs in a PLC, by PLC, test result signal judged and process and compare with the resistance of setting, on PLC, be also connected with the warning device that can report to the police, PLC controls a servomotor that can drive the main shaft of control switch simultaneously, wherein, control switch is the product in Figure of description.
